'Ihis invention relates to an improved shoe and method of manufactureand has for one of its principal objects the production of a shoe or thelike in a relatively simple manner, with a minimum of labor and withoutthe use of expensive or complicated machinery.

One of the important objects of this invention is to produce a shoewhich is simply and easily built but which, at the same time, will besturdy and long lasting.

Another and further important object of the invention is to provide ashoe constructed by a simple method and composed of a minimum number ofparts stitched or otherwise fastened together in such manner that thewearing qualities of the shoe itself will be considerably enhanced.

Other and further important objects of the invention -will be apparentfrom the exposures in the accompanying drawing and followingspecification.

The invention, in a preferred form, is illustrated in the drawings andhereinafter more fully described.

In the drawings:

Figure 1 is a side elevation of the improved shoe of this inventionshowing a particular type of shoe but it will be obvious that variousother types of shoes can be constructed by the method of this invention.

Figure 2 is a bottom plan view showing the first stage or step in themanufacture of the improved shoe of this invention.

Figure 3 is an enlarged sectional View taken on the line 3-3 of Figure 2looking in the direction indicated by the arrows.

Figure 4 is a plan view showing the inner face of the outsole which isused in the construction of the improved shoe of this invention andillustrating more particularly the method of mounting the shank tuckupon the inner face of the outsole preparatory to assembling theout-sole and shank tuck with the previously assembled insole and upperillustrated in Figure 2.

Figure 5 is a sectional view taken on the line 5--5 of Figure 4, lookingin the direction indicated by the arrows.

Figure 6 shows a modification of the invention embodying a diierent shoewhich includes a toe portion and a slightly different mode ofconstruction.

Figure '7 is a longitudinal sectional view taken on the line 'I--1 ofFigure 4.

Figure 8 is a section of one edge of the shoe taken on the line 8-8 ofFigure 1.

Figure 9 is a section of one edge of the completed shoe takensubstantially on the line 9--9 of Figure 4, but including the assemblageof all the essential parts of the shoe.

As shown in :the drawings:

The reference numeral I0 indicates generally the upper of the improvedshoe of this invention which is shown as being of the toeless type, butthe invention method may be used to produce shoes of almost any type,within limits.

The shoe is shown as having what is known as a mud-guard which isillustrated at I2, but this mud-guard may be dispensed with if desired.The out-sole of the shoe is indicated at I4 and the insole at I6. Thisinsole is sometimes called the sock lining.

The first step in the manufacture of the improved shoe of this inventionconsists in sewing or stitching the mud-guard I2 to the upper IU, thisconnecting line of stitching being obviously around those edges pf theupper which are eventually fastened to the corresponding edges of theout-sole. Obviously, When the mud-guard is not employed this step isomitted.

The sock lining or insole I6 is then attached to the upper Ill by lineof stitching I8 as best shown in Figures 2 and 3. The correspondingadjacent edges of the upper I0 and the insole I6 are aligned as shown inFigure 3 previous to the stitching operation. The stitches which connectthe mud-guard I2 to the upper I0 are indica-ted at 20 in Figures 3 and9.

The cuit-sole I4 then has the shank tuck 22 applied to its inner face inthe manner illustrated in Figure 4. As shown in this figure, the shanktuck 22 has its forward edge widened to correspond to the width of theadjacent portion of the out-sole I4. Two lines of stitching 24 and 26are then employed to fasten the forward edge of the shank tuck to theout-sole and a series of nails or the like 28 serve to attach the rearend of the shank tuck :to the corresponding heel portion of theout-sole. The shank tuck ordinarily includes a steel reinforcing stripas shown at 30.

The two portions of the shoe, namely, the assembled upper and insole andthe assembled shank tuck and out-sole are then brought togetherpreferably upon a last as indicated at 32 in Figure 6 after which themud-guard or the outer edges of the assembled upper and insole are thencemented to the corresponding edges of the out-sole after which theparts are then stitched together by final line of stitching as indicatedat 34 in Figure 9 and also in Figure 8.

The shoe illustrated in Figure 6 has no mudguard but the upper 40 issimply flared out at the edges as shown at 42 and after beingpreliminarily united to the insole which is not shown in this case, thepreliminarily joined elements `are then assembled with the out-sole 44in the same manner as previously described.

It will be seen that herein is provided a novel yet Well built shoewhich is simple of construction and readily manufactured with a minimumof labor and without any diflicult assembling opera tions, not tomention the fact that no cumbersome or expensive machinery is requiredfor production.

The shank tuck 22 may alternatively be cemented or otherwise fastened tothe insole i6 instead of to the out-sole I4 and this ,operation willthen comprise a, part of the first or preliminary step in the assemblyof the improved shoe of this invention. Also, the shank tuck, when it isfastened `to the out-sole I4 can be glued thereto and the lines ofstitching 24 and 26 shown in Figure 4, be `accordingly dispensed With.

I am aware that many changes may be made and numerous details ofconstruction Varied throughout a Wide range Without departing from theprinciples of this invention and I therefore, fdo not purpose limitingmyself in the patent granted hereon otherwise than as necessitated bythe prior art.

I claim as my invention:

A method of manufacturing shoes comprising preliminarily fastening amud-guard to the shoe upper with the edges of the mud-guard projectingbeyond the edges of the upper, then stitching an insole to the combinedmud-guard and upper With the edges of the insole and the edges of theupper in alignment, assembling a shank tuck to an outsole and thenapplying the assembled shank tuck `and out-sole to the mud-guard, Whileall the parts are positioned upon a last, the edges of the mudguard and`out-sole being in alignment.
